宇宙学与中微子性质

Cosmology and Neutrino Properties

A. D. Dolgov

摘要:

本文简要介绍了中微子的宇宙学影响以及宇宙学对中微子性质的限制。本文讨论了中微子质量的上界及其可能的弛豫方法,宇宙中微子本底的观测方法,中微子振荡对宇宙轻子不对称性的极大改善,中微子自旋统计定理破缺的宇宙学效应,考虑活动中微子振荡时活动中微子和可能的惰性中微子混合参数的界,右手电流和中微子磁矩的界限,还有更多。

英文摘要:

This is a brief review for particle physicists on cosmological impact of neutrinos and on restrictions on neutrino properties from cosmology. The paper includes discussion of upper bounds on neutrino mass and possible ways to relax them, methods to observe the cosmic neutrino background, bounds on the cosmological lepton asymmetry which are strongly improved by neutrino oscillations, cosmological effects of breaking of spin-statistics theorem for neutrinos, bounds on mixing parameters of active and possible sterile neutrinos with the account of active neutrino oscillations, bounds on right-handed currents and neutrino magnetic moments, and some more.
